Answer:
upper bound = 112.5
lower bound = 111.5
Step-by-step explanation:
x = 360 - 59 - 108 - 81
x = 112°
upper bound = 112.5 < 113
lower bound = 111.5 < 112
so
L.B. U.B.
111.5 < 112 < 112.5
Answer:
x = -3 or 9/4
Step-by-step explanation:
(x+3)(4x-9)
or use the quadratic formula
Shannon's scooter has a piece of tape stuck to the tire. If
the tire has a diameter of 18 inches, the distance traveled by the piece of
tape in 72 degree rotaion can be solve using:
S= ra, where s is the distance traveled, r is the radius and
a is the angle in radians
s = (18in/2)(72 degree)(pi/180 degrees) = 11.31 in.
T < 5/2
t is less than 5/2 or 2.5
13 + 22 x 13-(-22) =783
Rules of addition and subtraction are :
1. - x - = +
2. + x - = -
3. - x + = -
In English, minus(-) multiplied(×)by itself(-) equals to addition(+).
Plus sign (+)or addition multiplied by minus equals minus :) be happy
